Hi, Erik. Thanks for the email.

I'm not really sure how to create a package. Is there a reason why the single package can't have both static and dynamic options?  I would think that the --static flag would be used to determine which of the two libraries would be used. 

In any event, I have been able to compile a static version and am using it locally. Yes, I'd like to make a package, if you can point me to directions. 

Regards,

Simson
